Reasons for solar thermal success in Greece
   The conventional source of water heating is electricity,
    with higher costs than fuel oil or gas, leading to
    shorter payback periods for solar systems.
    Most houses have a flat roof, enabling the easy
    installation of an inexpensive thermosiphon water
    heater.
   Favourable climatic conditions.
    State support during the start-up phase of solar
    thermal.
   Involvement of dedicated individuals at the early
    stages of solar thermal.
